<p>A simulation experiment was used to understand the importance of riparian vegetation density, channel orientation and flow velocity for stream energy budgets and river temperature dynamics. Water temperature

<p>The effects of climate change and variability on river flows have been widely studied. However the impacts of such changes on sediment transport have received comparatively little attention. In part

Recent news on the occurrence of off-seasonal natural disasters, such as pre-monsoon drought and post-monsoon flooding in India and particularly in the peninsular region, highlight the urgent need to look at the patterns of change in seasonal extremes at the local level.

<p>The water resources of a Miocene limestone aquifer in northwest Sri Lanka were investigated. The limestone aquifer receives recharge although it is buried beneath a thick sequence of Quaternary deposits of low permeability which cover the whole basin. Hydrochemical and pumping-test data show that this recharge occurs as leakage through the semi-permeable cover.
